Abstract:

In order to determine how the quantity of curve in different proportions in the aggregate affects the mechanical properties of concrete, this study has experimentally studied the effects of the curve content in the aggregates used in traditional concrete production on the characteristics of concrete. For this purpose, with reference concrete samples in various proportions of fine aggregate amount of 5%, 10%, 15%, 20%, standard cube and curvature samples were produced in five series. In the framework of the studies, the production of fresh concrete (breakdown) is low, and the ultrasound transition speed in solid concrete cube samples, pressure resistance experiments and curvature samples, as well as curvation experiments have been conducted. According to the results of the trial, the increase in the freezing rate in fresh concrete has increased the level of processability, while the increase in the freezing amount in solid concrete has significantly reduced the pressure and inclination resistance. With the increase in the amount of silk, the amount of collapse in fresh concrete increased at rates of up to 43%, the pressure resistance was reduced by 39% and the inclination resistance was reduced by 84% and the ultrasound transition speeds were also reduced along with the increased silk rate.
